Question

I keep getting the following message when I turn on my computer, and I don't know what to do...

"Windows could not start because the following file is missing or corrupt: WINDOWSSYSTEM32CONFIGSYSTEM

You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM.
Select 'r' at the first screen to start repair."

When I put in the original CD, nothing happens either.

Is there any way to also save my files? I have a lot of pictures on there that I want to keep.

Thanks!
